Tech firms eagerly await Alt HAN Invitation to Tender (ITT)

Press Release
Published: 18 October 2017

 The Alt HAN Co is reaching out to technology vendors ahead of the soon to be released Invitation to Tender (ITT) for Alternative Home Area Network technologies and solutions.


It follows the success of the recent Vendor Engagement Event held in late August by the Alt HAN Co, which saw close to 40 different organisations attend and discuss the Alt HAN procurement approach and technology design.


The session proved invaluable in encouraging discussion and finalising a procurement approach. Vendors that have expressed an interest will receive an NDA, which must be completed prior to receiving an invitation to tender.  On or around the 25th October 2017, the invitation to tender will be released and vendors will have until early December 2017 to respond.


“This is an exciting time for Alt HAN Co as we approach the first major milestone of the technology procurement”, said Colin Sausman, Alt HAN Co Chair. “We are encouraged by the interest received so far and want to continue to reach out to any other technology solution designers so we secure the best possible result for GB energy customers.”


Alt HAN Co has also distributed a FAQ briefing based on questions raised by vendors who attended the Vendor Engagement Event, 1-2-1 sessions or contacted Alt HAN Co directly. Additional copies are available on request.


Interested vendors can still submit an expression of interest to AltHANProcurement@gemserv.com.


This is part of the programme to install SMART electricity and gas meters to all residential and small business customers in GB by the end of 2020.  The new Alt HAN technology is needed to address 3.5% of buildings where the currently planned smart metering solutions are likely to be difficult to deploy due to device to device communication restrictions.

IREG Update October 2017

IREG met on 11th October 2017 and discussed the following:

MIF219 – Accuracy of Working Practice Product Set (WPPS)

  • Working Practice (WP) 16 (MPAS – Differentiation between Supplier Full or Partial Refresh (D0204)) – IREG agreed that the details can be added to MRA Agreed Procedure (MAP) 04 (Error Resolution and Retrospective Manual Amendments). However, IREG noted that this would require a wider review of the MAP, therefore agreed to close WP16 from MIF219 and for a separate MIF to explore this.
  • WP66 (Change of Measurement Class – NHH to HH) and WP116 (Change of Measurement Class from NHH to HH Coincident with CoS) – IREG agreed that WPPS Change Proposals (CPs) should be raised to remove these WPs as the detail was captured in relevant Balancing and Settlement Code (BSC) Procedures (BSCPs).
  • WP144 (The use of Site Visit check codes 02 and 20) – IREG agreed that the WP could be removed, however, believe that the rules would be better accommodated with the BSCP where the processes which use the codes are outlined. ELEXON to consider raising a BSC change to include the codes.
  • WP147 (Auxiliary Metering Information) – IREG noted that this was originally a short-term solution pending DTC changes that have since come in to effect. As such, WPPS CP should be raised to remove this WP.
  • The next WPs to be reviewed will be WP6 (Determining the Meter Reading on Change of Supplier (MRoCoS)) and WP150 (Advanced Meters: Auxiliary Metering Information)

MIF225 – Update on legal counsel for Intellectual Property drafting

Gemserv presented the responses from the MRASCo lawyer on the clarification questions. IREG noted the responses, but still was not clear on what the issue the MIF intended to address was nor why the MRASCo Board wanted IREG to consider the MIF. As such, this was passed back to the Board to clarify.

MIF235 – Review of MAP17 MIF process

IREG agreed amendments to both MAP17 (Issues Resolution and Change Management) and the IREG Terms of Reference to better clarify the process and timings for the progression of MIFs.

Gemserv is making MIFs available via the MRASCo website in the short-term, though there are issues with those that do not include an implementation date. The new website requirements include these in the Change Tracker as the long-term solution.

MIF237 – Contract Manager Guidance Document

The draft document produced by the Erroneous Transfers Working Group (ETWG) is still under development following previous IREG comments and will be presented to the next IREG.

MIF238 Changes to WP152 Requesting Additional or New MPANs

IREG considered the processes and noted that the Proposer will work with a Supplier to bring either an amended MIF or new MIF to the next IREG.

MIF239 – Permissible symbols included in email addresses which appear in dataflows sent through the DTN

This MIF seeks to address issue highlighted in the impact assessment of DTC CP3515 (Allowing the use of an underscore). Specifically, that the CP had not gone far enough to encompass enough symbols in the J1844 (Customer Preferred Contact Details) or J2060 (Contact Email) that were leading to customer email rejections.

IREG agreed that the J0012 (Additional information), where this is used in the D0012, was also relevant. However, it also considered the potentially large number of flows to be affect if the J0012 is included in this MIF, and the amount of testing that would be required by parties. As such, it agreed to determine the most frequently rejected email addresses characters within the last six-months.

MIF240 – Missing Register Mapping Coefficient for Non-Settlement Meter on D0367’

IREG noted that the D0367 (Smart Meter Configuration Details) was created following the approval of BSC Modification P302 (Improve the Change of Supplier Meter read and Settlement process for smart Meters). It therefore asked ELEXON to consider whether there were reasons why Register Mapping Coefficient for Non-Settlement Meter were not included in the Data Flow at the time.

MIF241 – Enabling identification by gaining Supplier of a Customer Preferred Agent

The initial discussion of this MIF explored one of the three potential solutions previously discussed under closed MIF234 (Potential Change Proposals to improve BSC processes in identifying and managing Customer Preferred Agents). The other two associated MIFs will be addressed at a future IREG.

IREG considered the two broad solutions of either ECOES changes or DTC changes with amendments to the registration process. However, noted issues with both options. ELEXON agreed to consider the feedback and come back to the next meeting with either a more detailed solution for consideration; or to close the MIF if it agrees that the costs and issues it introduced outweigh any perceived benefits.

MIF244 – Review of SPF102 following Impact Assessment – Review solution

MIF244 was raised to allow IREG to consider the responses to Solutions Pre-Assessment (SPF) 102 (Interoperability in the sub 100kW Half Hourly Market Post P272). IREG suggested several amendments and alternative approaches to the proposed solution. The focus of these was to avoid any unnecessary changes to Distribution Businesses systems that D0268 Data Flow changes would introduce. Following feedback from IREG, the Proposer agreed to review the suggestions and bring updated solution drafting back to the next meeting for further discussion.

Next meeting

IREG will next meet on 8th November 2017.
